Suppose you wish to measure the current in a wire. You have a device that can measure the strength of the magnetic field produced by the wire, but the device does not directly measure the current. If the device is place 2.4m away from the wire, and the magnetic field strength is 0.22μT, what is the current running through the wire in Amps?

The Hall effect can be used to determine the density of mobile electrons in a conductor. A thin strip of the material being investigated is immersed in a magnetic field and oriented so that its surface is perpendicular to the field. In a particular measurement, the magnetic field strength was 0.723 T, the strip was 0.107 mm thick, the current along the strip was 2.83 A, and the Hall voltage between the strip's edges was 2.73 mV.

An electromagnetic rail gun uses magnetic forces to launch projectiles. (Figure 1) shows a 10-cm-long, 12 g metal wire that can slide without friction along 1.0-m-long horizontal rails. The rails are connected to a 300 V source, and a 0.10 T magnetic field fills the space between the rails. Each rail has linear resistivity λ = 0.10 /m, which means that the resistance is A multiplied by the length of rail through which current flows. Assume that the sliding wire and the left end, where the voltage source is, have zero resistance. The wire is initially placed at x0 = 30 cm, then the switch is closed.
